1b (1.350.072.0711 it may concern:

Be it known that l, .tinssnnr. S. CARTER, a

citizen or the United States, residing in Hewlett, Nassau county, New York State, have invented the following-described Iniproveinents in Slioclr-. .bso1'be1:' Connections.

The improvement relates to shock-ab sorbers of the kind wherein a rotary mom-- ber confined in a casing modifies or assists the action of the springs of a vehicle taking up shocks, and provides a simple and convenient form of adjustable connection for such devices whereby they may be readily applied to various kinds of vehicles and adjusted thereon to accommodate the normal compression of the springs thereof, as hereinafter explained and more particularly pointed out in the claims.

In the accompanying drawing illustrating the invention: Figure 1 is a side view of a shoclcabsorber of the elbow type ap plied between the frame of an automobile and its axle by means of this invention. Fig. 2 is a plan view of the same, partly in section.

l hile the invention is not confined to any particular type of shock absorber, I have illustrated the same herein as used with a dash pot shock absorber in which the piston member is a stiii spring blade adapted to react on the springs of the vehicle through. its connections, and retarded by the' 'inertia and friction of a body of liquid confined a casing. Such shock absorber forms the subject of a pending application, Serial No. 771,614, filed by me on June 4th, 1913, to which reference may be had for the details of construction thereof. The casing l of such absorber. is of general sector shape provided with parallel side walls which are vertical when the absorber is coniocted to the vehicle. The spring blade 2 is set in a hub 3 which is journaled in the casing; with. one end projecting to theeXterior thereof and also squared to receive an arm 4 held thereon by means of a screw, nut or otherwise. The free end of the arm 4 is pivoted to a stud 7i projecting from a plate 6, which can be attached to one oi the two members between which shock is to be absorbed, for instance to the side girder Y of an automobile. ln order to secure the casino: 1 to the other of the parts between which shock is to be absorbed, for EXHd'll 'lQ to the'aXle 12 of the automobile, provide a boss 8 on the T casing which is preferably concentric with.

the hub 3 forming a part ofthe hearing which the same has upon the casin G11 this boss lswivel. a second arm 9, about equal in length to the arm a and capable of being clam-pod against the casing in dii' ferent angular relations thereto. For this purpose the casing is provided with an arcuate bolt slot formed in a flange near its curved end wall, and one or more bolts 10 are passed through this slot and through the arm 9 as shown in the drawing. The free end of the arm 9 is adapted for pivotal con nection with the axle 12 by means of a stud 11, or otherwise. both dbrergent arms have been thus pivotally fastened to the parts of the vehicle the casing; 1 may then be turned on its hub, and in the arm 9, until the spring blade or piston member 2 thereof is brought to a normal or centralized position therein such it should occupy when the vehicle frame and axle are separated by a normal distance, that is to say when the vehicle is supporting its normal load. It is essential that the casing be set so that the spring blade shall not strike it at either end of its oscillation and for this purpose it must occupy a substantially mid position under normal running conditions. The bolts 10 are tightened when the casing has been thus adjusted and the device isrcady for service. A snark formed on the end of the hub or elsewhere serves to indicate the angular relation of the blade (which is within the casing) with relation to the arm 4 andas an assistance in making the described adj ustmcnt.

It is preferred that both arms, and. 9, be disposed upon the same side of the casing 1, and also thatthe arm 9 shall be con centric with the hub and sector-shaped casing, but the invention is not confined to any specific location of the said. parts, provided they function in the manner indicated and except as specifically pointed out in the appended claims.

I claim:

1. An elbow type shock-absorber for vehicles, comprising in combination a closed licuiid-contaiuing casing, an oscillatory piston member therein, having a hub, two divergent lever arms concentrically disposed with reference to the hub and provided with means at their free ends for .pivotully connecting them respectively to the parts between which shock is to be absorbed, one of said arms being fixed to the hub and. the

lVhen the outer ends of confining casing having poroother being movobly cngagccl to the vcrifiicsl side wall of the casing and provided with clamping" means whci'cby said closed casing may be scoured thereto in (liflorent angular positions.

2. A vehicle shock-absorber, comprising a closed liquid-containing casing having parallel vertical side Walls, an oscillatory piston therein having a hub, s lever arm on such liuo adapted at its outer cod for connection with one of the ports between which shock is to be absorbed, and o member ad jus'tobly secured to one of the saicl vertical side walls and adopted for connection $0 the other of the ozmhs between which shock is to be absorbscl A vehicle shock-absorber comprising a closed substantially S8Ct0P-Sl1flfid liquidilsl vcrcicol side walls, an oscillating piston bctwccn such walls and s hub for the piston projecting to the exterior thereof, in combination Wish a. pair of members respectively connecting said hub and casing to the parts between which the shock is so be absonbci, both of said mcans'being on the some side oi the olosccl casing and. one of them losing agustably fixccl to the proximate vc'rticoi snio wall thereof, whereby the casing conho ccntorool with rfcrencs to the pislnn-thoio 4-. A vehicle shocl'oobsoifbcr compiising s closed. liquid-containing casing; liming; on oscillatory piston libercin and :2, lit-3 2? f' or said piston extending to the exterior of tho casings lever mm on said hub, s boss on who casing, a second arm member hinged to such boss and means for fixing she latter member in diilercnt angular positions with refcrcncc to said boss,

5. A vehicle shock-absorber comprising a closed liquid-containing casing, an oscillacing piston flicrcin connected to one of tho pan-ts between which shock is to be absorbed, and. means for securing the casing to the other of the parts between which shock is to be absorbed, comprising a member pivotally mountcrl at one point on the casing and having a bolt-ond-slot connection at o remote point with said casing.

6. A vehicle shock-absorber comprising 2 closed liquid-containing casing, an oscillasing piston therein having a hub, and a lover arm fixed to such hub in combination wish a boss on. the casing surrounding the hub, 21 member pivotally mounted upon the said boss, and moons remote from the boss ior scouring said member in cllfiersnt angulair nositions to the casing.

In testimony whereof, I hails signed this specification in the presence of two witnesses V RUSSELL S. CARTER.
